BUILDERS HARDWARE.

Specification of Letters Patent.

Patented Au 29, 1916.

Application filed April 10, 1916. Serial No. 90,085.

To all whom it may concern Be it known that I, JAooB S. DETRIOK, a citizen. of the United States, residing at Baltimore city, in the State of Maryland, have invented a certain new and useful Improvement in Builders Hardware, of which the following is a specification.

My invention relates to improvements in builders hardware wherein a plurality of cooperating members act to prevent jamming or interlocking of swinging bodies.

It has for its object adjustable means of reciprocally adjusting cooperating parts to the work required. And a further object of myinvention is the providing of means of preventing interfering vibrating bodies from interlocking.

With the foregoing and other objects in view my invention consists of the novel construction, combination and arrangements of parts as herein specifically described and. illustrated in the drawings wherein is shown the preferred embodiment of my invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawing of the herein described embodiment of my invention, Figure 1 shows an enlarged plan view of one of my cooperating members; Fig. 2 being a view in elevation of that shown in Fig. 1; Fig. 3 is an end view of that shown in Fig. 1; Fig. 4 shows the application of my cooperating members to swinging bodies in plan view; and Fig. 5 is a view in elevation of that shown in Fig. 41.

Similar numerals refer to similar parts throughout the several views.

1 are the sides of the frame, 2 being its back.

3 are adjustable arms.

4 is a roller ournaled on pin 5 which pin secures arms 3 together at their outer end. Arms 3 are fulcrumed on pin 6, are spaced apart by bushings 7 and 8 and locked in position by bolt 9 and thumbscrew 10 which bolt operates through slot 11 in sides 1.

12 and 13 are swinging bodies swinging on pivots 14 and 15. Back 2 is secured to swinging bodies 12 and 13 by screws, bolts or other suitable means so that one is above the other to prevent interfering as shown in Fig. 5 and arms and rollers are adjusted mutually to simultaneously contact one with the other swinging body to which it is not attached and the other to the swinging body to which the first one is secured.

The operation of my invention is as follows: One of my cooperating members being attached to each of the swinging bodies as shown in Fig. 1 and reciprocally adjusted as there shown they simultaneously leave .and enter their sphere of action reciprocally acting one to prevent the other swinging body from becoming fouled.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. In builders hardware a plurality of cooperating members in combination with a plurality of swinging bodies operating partially in a common zone whereby the cooperative member attached to one body controls the movement of the other body with respect to the body to which it is attached when in the zone of interference and is free of contact of the other body at other times.

2. In builders hardware a plurality of cooperating members in combination with a plurality of swinging bodies operating partially in a common zone whereby the cooperative member attached to one body controls the movement of the other body to which it is attached when in the zone of interference and is free of contact of the other body at other times and means of relatively .adjusting one member to the other.

3. In builders hardware a plurality of coiiperating members in combination with a plurality of swinging bodies operating partially in a common zone whereby the cooperative member attached to one body controls the movement of the other body with respect to the bodymto which it is attached when in the zone of interference and is free of contact of the other body at other times and means of relatively adjusting one member to the other consisting of means of adjustably securing a fulcrumed arm fulcrumed in one member at a desired point of adjustment with reference to the swinging body upon which its reciprocal member is secured.
